Sobolev spaces are a class of function spaces that play a crucial role in the study of PDEs and optimization problems. These spaces are defined as follows:
with boundary conditions \(u=0\) on \(\partial \Omega\) . This PDE can be rewritten as an optimization problem: Sobolev spaces are a class of function spaces
$$-\Delta u = g \quad \textin \quad \Omega Sobolev spaces are a class of function spaces
